"""This is a function that initializes a signal class using a dictionary
of parameters.
It either uses the dictionary set when Simulation() is called, if
signal_dict is left as None, or a dictionary that is input directly
into the init_signal function. mode is automatically set to 'simulate'.
Parameters
----------
signal_dict : dict, optional
Required keys of this dictionary are parameters
(Key : Value type/possible values)
f0 : float
Central frequency (MHz).
bw : float
Bandwidth (MHz).
Nf : int
Number of frequency bins.
f_samp : float
Sampling frequency (MHz).
ObsTime : float
Total observation time in milliseconds.
data_type : {'int8', 'int16'}
Automatically changed to 'uint8' or 'uint16' if intensity signal.
SignalType : {'voltage', 'intensity'}
'intensity' which carries a Nf x Nt filterbank of pulses or 'voltage'
which carries a 4 x Nt array of voltage vs. time pulses representing
4 stokes channels
